PAPER-FILE.

Specification of Letters Patent.

Application filed May 28, 1913.

Patented Jan. 20, 1914. Serial No. 770,465.

To all whom it may concern Be it known that I, WILHELM BODLAENDER, acitizen of the Empire of Germany, residing at Karlsruherstrasse 8,Berlin-Halensee, Germany, have invented certain new and usefulImprovements in Paper Files, of which the following is a specification.

My invention relates to improvements in paper files in which the sheetsof paper are not punched but held by the clamping action of a pressuremember.

The object of the improvements is to provide a paper file of this classwhich is simple in construction and reliable in operation.

With this object in View my invention consists in providing on the innerside of the file wrapper a hinged elastic bail provided withcomparatively short side arms and made integral with an operating arm,which is adapted to be locked in closing position by engaging below alocking nose, the said elastic bail clamping the sheets of paper byengaging the same at the rear of a clamping edge located below thesheets and in front of the bail. The ressure which is thus exerted bythe locklng arm cooperates with the elasticity of the bail in such away, that a reliable clamping action is produced with a full file aswell as with a file which contains a small number of sheets.

For the purpose of explaining the invention an example embodying thesame has been shown in the accompanying drawing, in which the sameletters of reference have been used in all the views to indicatecorresponding parts.

In said drawin Figure 1, is a plan view of the open file, Fig. 2, is alongitudinal section of the clamping mechanism of the file taken withthe cover or wrapper removed, and Fig. 3, is a cross-section taken onthe line BB of Fig. 1 with the cover removed.

To the inner side of the wrapper a a strip of sheet metal 7) is securedwhich is bent upward at its outer end so as to produce an upturnedclampin edge 0. To the said strip a ocket d o U-shaped section issecured, w ich is adapted to receive the sheets of paper at the innermargins thereof. To the upper and lower ends of the strip 1) metalstrips 6 and f are secured which at their inner ends are bent into theform of eyes providing hinge bearings for a bail g. The side arms 72, ofthe said bail are com- 5 paratively short, and they are so long, that inthe clamping position the bail acts on the sheets of paper at the rearof the clamping edge 0. The end of the bail which is supported in thestrip 6 has an extension or arm is which is bent at. a right angle andis formed at its end with a finger piece 2', so that when depressing thearm 70 at its end i the whole length of the arm 70 operates by itsleverage to press the bail g on the pocket or the papers placed therein.The bail g is curved downward, and by its elasticity it is bent in sucha way that it engages the sheets over the whole length of the same withuniform pressure, and that its clamping action is effective even in casethe pile of paper is but small. The strip e is provided with an upturnedportion Z formed with a nose m which is engaged by the arm 75 whendepressin the same. When being thus depressed the said arm slidesdownward on the inclined upper edge of the nose, and it is bentlaterally, so that it engages by spring action below the nose.

In Fig. 3 the full lines show the bail in its clamping position, whilethe dotted lines show the same in its open position in which the sheetsof paper are released.

Fig. 2 shows the bail in the position in which it is in contact with thesheets of paper but is not yet pressed thereon and bent into straightform.

In Fig. l the bail is shown in its clamping position.

I claim herein as my invention:

1. In a paper file, the combination with a foundation providing asupport for the sheets of paper, of an elastic bail curved toward thesupport and hinged thereto, an operating arm for said bail, and means tolock said arm in clamping position.

2. In a paper file, the combination with a foundation providing asupport for the sheets of paper, of a strip on said support formed withan upturned clamping edge, an elastic bail curved toward the support andhinged thereto, an operating arm for said bail, and means to lock saidarm in clamping position.

3. In a paper file, the combination with a foundation providing asupport for the sheets of paper, of a strip 011 said support formed withan upturned clamping edge, an elastic bail curved toward the support andhinged thereto and extending with its clamping part at the rear of theclamping edge, an operating arm for said bail, and nose provided on thesupport and located 10 means to look said arm in clamping posipositionfor looking engagement with sald tion. arm.
